How does the rib cage protects the heart and lungs?
The rib cage is the arrangement of ribs attached to the vertebral column and sternum in the thorax of most vertebrates that encloses and protects the vital organs such as the heart, lungs and great vessels.
How ribs play a major role in protecting lungs?
Ribs muscles: The ribs help in the expansion and contraction of the thoracic cavity and also protect the lungs and heart. When the diaphragm expands or contracts, the thoracic (chest) cavity expands or contracts, alternately pulling in the air (inhalation) or expelling it (exhalation).
How does the rib cage protect the body?
The bones of the chest — namely the rib cage and spine — protect vital organs from injury, and also provide structural support for the body. The rib cage is one of the body’s best defenses against injury from impact. Flexible yet strong, the rib cage protects major vital organs such as the heart, lungs, and liver.
How many ribs cover the lungs?
A bony cage (commonly called the rib cage), which is formed by the sternum, ribs, and spine, protects the lungs and other organs in the chest. The 12 pairs of ribs curve around the chest from the back.
Why are the ribs important for breathing?
The purpose of the rib cage is to be the attachment for our respiratory muscles in order to aid in breathing, as well as, serve as a protective shield for the vital organs (the heart, lungs, and major blood vessels).
What important activity takes place in the lungs?
The main function of the lungs is the process of gas exchange called respiration (or breathing). In respiration, oxygen from incoming air enters the blood, and carbon dioxide, a waste gas from the metabolism, leaves the blood.
How are the ribs adapted to their function?
Ribs are long, curved bones that form the rib cage surrounding the thorax. The thoracic cage can expand and contract to facilitate breathing in association with the diaphragm; it also protects the lungs, heart, and other organs of the thoracic cavity.
